Application led March 26, 1927. Serial No. 178,543.

scribed, a shield or protector for `small plants which may be used when desired to prevent the plants in the row from being covered with learth `from the cultiva'tor shares.

A. lstill 'fufrth'erffeature of the invention 'resides in the provision of an attachment which may be Areadily applied to the conventional 'type of cultivator for the purpose of blocking or thinning 'out the plants in a row. y

With the abovfe and other yobjects in View the invention has particular relation to certain novel features of construction, operation and arrangement of parts, an lexample .of which is given in this sp'eciticationand illustrated in the accompanying drawings, wherein `Figure 1 nshows a side 'elevation of the implement, and y Figure 2 shows a fragmentary front elevatio-n thereof.

Referring no ence designate similar parts in each of the figures, the numeral 1 designates the cultivator axle which is of an inverted U-shaped form and which has the outwardly turned spindles 2, 2, on which the ground wheels 3 are rotatably mounted. Fixed to the upper partr of the axle there is a forwardly extending tongue 4, provided for the attachment of draft animals to the implement. In front of the ground wheels and underneath the tongue there is a cross bar 5 and fastened to the respective side arms of the axle are the side members, as 6, of the framework, whose forward ends are anchored to the cross bar 5. Fastened to the forward end of the respective side members 6 are the hanger rods as 7, whose lower ends are connected to the forward ends of the rearwardly extending beams 8 and clamped to these respective beams and depending inore particularly to the; drawings, wherein like numerals of refer-y vtherefrom are the stocks 9 whose lower ends have conventional shares 10 fastened thereto, said shares beingiarranged to" pas's'on opposite sides of the ro'w to 'becultivated.V The rear ends of thebeams are supported from the axle by means of suitable i uyjrods, as 11. Each hangerv rod 'Tis'provide lwith the clamp 12 which is secured thereto andthe upV er'end `of the hangers 13 are vpivota'lly 'connected 'to the respective 'clamps 12. The Alower 'ends -of these hangers carry the bearing blocks 14, 14. There is a transyersefshaftlf, whose 'ends lare rotatably mounted in suitable vertical bearings r16 in the'res'pective blocks 14 and lcoil springs, as 17', are mounted yin vsaid 'bearings above the respective ends 'ofthe shaft 15. There is a drum' Vformed of end discs as 18 which are Vspaced =valp'airt 'and lixed on the shaft 15 and fastened to the margins `of these discs 18 and spaced apart are the slats 19. `These 'slats vare `'held yieldingly against the ground surface by the pressure of the springs 17. Mounted onthe axle 1 and extending rearwardly therefrom there is a seat support 2O carrying the drivers seat 21 and secured yIto lthesupport 2O there is a segmental rack 22 and depending from said support there is a bearing 23, towhich the lower end of the manual lever 24 is pivoted and extending forwardly from Athe lower end 'of said lever there is an arm 25 f whose forward end is pivotally connected to the upperendpf the 4lift yovkejcomposed of the arms 26, 26, whose lower ends are pivotally connected to the respective bearing members 14, 14. vA dog 27 is mounted on the lever 24 and adapted to engage the rack member 22 to hold the lever 24 in a predetermined position, said dog being operable in the conventional manner. Through the mechanism described the blocking drum may be elevated and lowered.

In operation, las the cultivator moves along the row, the drum will roll along on the sur* face of the ground and the slats 19 being spaced apart some of the plants in the row will be crushed andothers left standing and the following shares will throw the plowed earth over the crushed plants and the standing plant-s will be simultaneously cultivated.

There is an arcuate rearwardly curved supporting bar 28 whose respective ends are fastened to the arms 26 and this bar2'8 has a central bearing 29 through which the vertiA cal guard rod 30 works. The upper end of this rod has ahead 31 and surrounding said rod and interposed between the head 3l and the bearing 29 there is a coil spring 32. The

lower end of the rod 30 carries thev arcuate guard 33 which is normally held elevated by the spring 32. In case any of the plants left in the row are so small as to be liable to be covered by the shares the operator may apply his foot to the head 3l. and force the guard 33 downwardly into position to shield the plants to be protected and the guard, when in such depressed position, will ward off the earth thrown up by the shares. What I claim is v LAn implement of the character described including an. inverted U-shaped axle, ground wheels supporting the axle, a forwardly extending tongue attached to the upper part of the axle, a cross bar secured v to the tongue, side members lsecured at their front ends to said cross bar and at their rear ends to the side arm-s of the axle, hanger rods whose upper ends are connected to the forward ends of said side members, a

`clamp secured to each hanger rod, hangers pivotally connected to said clamps, a gearing block carried by the lower end of each hanger, a vertical bearing in each block, a transverse shaft whose respective ends are rotatably mounted in said bearings, a yield bar secured to said draft member, side members secured at their front ends to said cross bar and at their rear ends to saidaxle, hanger rods connected to and depending from the forward ends of said side members, a hanger pivotally connected at its upper en-d to each hanger rod, a bearing member carried by the lower end of each hanger, Va transverse shaft whose ends are rotatably mounted in said respective bearing members, a drum fixed on said shaft, said drum having plant spaces, a lift yoke having' side arms connected to the shaft bearings and means for elevating and lowering sai-d yoke.

3. An vimplement of the character described including an axle, ground wheels supporting the axle, a forwardly extending draft member attached to the axle, a cross bar secured to said draft member, side members secured at their front ends to saidy cross bar and at their rear ends to said axle, hanger rods connected to and depending from the forward ends of said side members, a hanger pivotally connected, at its upper end to each hanger rod, a bearing member car-v ried by the lower end of each hanger, a transverse shaft whose ends are rotatably mounted in said respective bearing members, a drum fixed on said shaft, said drum having plant spaces, a yoke for supportingthe drum, said yokev having side arms connected to the shaft bearings and means for elevating andlowering said yoke, said elevating and lowering means including a support carried by the axle, a -segmental rack secured to said support, a manual lever pivotally connected to said support, an arm carried by said lever pivotally connecte-d to said yoke and a manually controlled dogV carried by said manual lever and engageablevwith said rack. f i

In testimony whereof I have signed my name.
